Diverse symbionts of reef corals have endured since 'age of dinosaurs'

Thu, 09 Aug 2018 14:11:55 EDT ~ Coral-algal partnerships have endured numerous climate change events in their long history, and at least some are likely to survive modern-day global warming as well, suggests an international team of scientists. Find out more...

Effective method to control algae growth on Hawaiian coral reefs

Wed, 08 Aug 2018 19:36:38 EDT ~ Researchers have found a management approach that combining manual removal and outplanting native urchin was effective at reducing invasive, reef smothering macroalgae by 85 percent on a coral reef off O'ahu, Hawai'i. Find out more...

Corals are becoming more tolerant of rising ocean temperatures

Tue, 07 Aug 2018 09:51:51 EDT ~ Scientists replicate landmark study to determine changes in coral sea temperature tolerance over time. In the three species of Hawaiian corals retested, bleaching occurred later, with higher survivorship and growth rates than the same species of corals in 1970. However, scientists warn that temperatures are rising faster than corals can change. Find out more...

Some corals might adapt to climate changes

Thu, 02 Aug 2018 11:56:37 EDT ~ New research shows that not all corals respond the same to changes in climate. The study looked at the sensitivity of two types of corals found in Florida and the Caribbean and found that one of them - -mountainous star coral -- possesses an adaptation that allows it to survive under high temperatures and acidity conditions.

Predatory sea corals team up to feed on stinging jellyfish

Tue, 31 Jul 2018 09:20:35 EDT ~ Cave-dwelling corals in the Mediterranean can work alongside one another to catch and eat stinging jellyfish, a study reveals. Find out more...

Previously overlooked 'coral ticks' weaken degraded reefs

Thu, 26 Jul 2018 16:10:01 EDT ~ A previously overlooked predator -- a thumbnail-sized snail -- could be increasing the pressure on coral reefs already weakened by the effects of overfishing, rising ocean temperatures, pollution and other threats. Find out more...

NE Australian marine heatwave shakes up coral reef animal populations

Thu, 26 Jul 2018 08:59:55 EDT ~ Research describes upheaval among fish and invertebrate communities after a marine heatwave hit Australia's Great Barrier Reef and Coral Sea in early 2016. The study analyzed data collected across these areas by the Reef Life Survey (RLS) citizen science program. It identified important changes in reef-animal communities that may affect the resilience of coral reefs, potentially reducing the capacity of corals to rebuild after mass bleaching.

Deep-diving scientists say shallow reefs can't rely on twilight zone systems for recovery

Thu, 19 Jul 2018 14:21:33 EDT ~ A team of highly trained scientific divers explored Pacific and western Atlantic reefs to test a widely held hypothesis that climate-stressed life from shallow reefs can take refuge at mesophotic depths (100-500 feet beneath the ocean's surface). The results are clear: deep and shallow reefs are different systems with their own species, and deep reefs are just as threatened by climate impacts, storms, and pollution. Find out more...

Great Barrier Reef not bouncing back as before, but there is hope

Wed, 18 Jul 2018 14:31:09 EDT ~ The Great Barrier Reef is losing its ability to recover from disturbances, but effective local management could revive its capacity to bounce back. Find out more...

Eradicate rats to bolster coral reefs

Wed, 11 Jul 2018 13:12:01 EDT ~ New research has confirmed that invasive rats decimate seabird populations, with previously unrecognized consequences for the extensive coral reefs that encircle and protect these islands. Invasive predators such as rats -- which feed on bird eggs, chicks, and even adults birds -- are estimated to have decimated seabird populations within 90 percent of the world's temperate and tropical island groups, but until now the extent of their impact on surrounding coral reefs wasn't known.
